The MXS 5.0 is an advanced microprocessor-controlled battery charger that gives unrivaled performance for lead-acid batteries from 1.2-110Ah. It also includes battery diagnosis to establish whether your battery can receive and retain a charge, a patented automatic desulphation program, and an AGM option that maximizes the performance life of most Stop/Start batteries. The charger is splash and dustproof, designed to protect vehicle electronics and non-sparking, reverse polarity protected, and short-circuit proof batteries that cannot hold charge may need to be replaced. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery at 95100 % capacity.
